Base Address
This register is used to hold the address where the target device will
decode for I/O accesses. The size is 16K of addressing, naturally aligned.
This means that only bits 31-14 are writable. The PCI specification only
allows 256 bytes of I/O Base Address, so this address is only for special
applications. Using the feature of non-postable writes for I/O cycles must
accompany enough I/O space in the system memory map.
Reserved and set to ‘0’.
This is I/O space, so this bit is set to a ‘1’.
